End-to-End Digital Issuance, Registry & Settlement for Carbon Credits
Challenge

Many renewable energy and carbon reduction projects struggle to convert verified impact into credible, investable carbon credits. Fragmented measurement processes, manual reporting, inconsistent verification standards, and limited access to liquid markets prevent projects from realising the full value of their emissions reductions. As a result, significant carbon value remains locked, limiting revenue, cashflow, and scalability for project developers.
Solution
Measurement
We track projects’ energy and footprint data on-chain, creating an immutable source of data every step of the way.
Reporting & Verification
Using a 7-point methodology ensuring the offset’s validity, we calculate CO2 offsets and have them audited and verified.
Registry & Sale
The credits are registered and tokenized to ensure integrity and ease of transferability, selling these on through our marketplaces.
The partnership between Decarb.earth and ZERO13 delivers a fully optimised, end-to-end carbon credit solution. By combining IoT-enhanced data collection, on-chain measurement, third-party verification, digital registry infrastructure, and regulated marketplaces, the platform enables the creation, registration, and sale of high-quality carbon credits. Blockchain, smart contracts, and robust data methodologies ensure transparency, integrity, and trust across the entire lifecycle of each carbon offset.
Socio-economic protection is embedded directly into the financial and contractual framework, ensuring that a defined portion of project value is allocated to regional and community impact — not as a post-hoc promise, but as a system rule.
Outcome
Project developers gain access to previously unattainable revenue and predictable cashflow for carbon reduction initiatives, supported by trusted, auditable infrastructure.
Buyers and investors access high-integrity, traceable carbon credits, backed by immutable on-chain data and robust verification. Carbon credits become measurable, auditable, tokenised, and tradeable, available for sale on both spot and future markets.
Local communities benefit from protected socio-economic funding flows, strengthening project resilience, reducing political and reputational risk, and reinforcing long-term market confidence.
The result is improved liquidity, stronger investor confidence, and a scalable pathway for financing renewable energy and decarbonisation projects while maintaining rigorous environmental and governance standards.
How It Works
- Project Onboarding: Renewable energy projects are assessed and onboarded against a qualifying standard for carbon financing.
- Measurement: Raw energy and footprint data is automatically collected via smart meters, APIs, cloud aggregators, and inverters, with data tracked on-chain to create an immutable record.
- Methodology & Calculation: A regionally adaptable methodology calculates carbon emissions reductions and corresponding CO₂ offsets using automated systems.
- Verification & Auditing: Offsets are audited and verified using a 7-point methodology, with third-party auditors validating completeness, accuracy, and existence.
- Reporting: Smart-contract-driven reporting provides continuous, transparent reporting of emissions reductions to all stakeholders.
- Registry & Tokenisation: Verified offsets are registered and tokenised in a digital carbon registry, ensuring integrity and ease of transferability.
- Execution & Marketplace: Carbon credits can be sold, held, retired, or staked, and are traded through spot and future marketplaces, providing liquidity and access to global buyers.
ZERO13’s 7Cs

Climate:
Verified emissions reductions are generated through IoT-enhanced decarbonisation projects, delivered through auditable, data-driven infrastructure.
Carbon/Commodities:
Carbon credits are measured, verified, registered, tokenised, and settled end-to-end on digital infrastructure, turning into high-integrity, traceable, and tradeable carbon assets.
Capital:
Previously locked climate value is converted into predictable revenue and cashflow through spot and future carbon markets, unlocking private capital to fund and sustain long-term decarbonisation initiatives.
Communities:
Socio-economic value is protected by ensuring carbon revenues flow back to projects on time and transparently, strengthening local livelihoods, project resilience, and long-term community trust.
Companies:
Project developers and corporate participants gain access to institutional-grade infrastructure that improves pricing, reduces settlement risk, and supports scalable participation in voluntary and compliance carbon markets.
Countries:
Digitised registries and auditable MRV data support national climate objectives, reduce double-counting risks, and strengthen credibility with regulators, investors, and international markets.
Connectivity:
ZERO13 connects IoT data, third-party verification, registries, custodians, and marketplaces into a single interoperable digital value chain, eliminating fragmentation across the carbon credit lifecycle.
